Spherical Roller Bearings – Spherical roller bearings consist of an outer ring with a spherical raceway and an inner ring with a double-raceway, one or two cages, and one group of spherical rollers. As the center of the spherical raceway of the outer ring coincides with the center of the bearing, it makes it have the self-aligning property. Spherical roller bearings can adjust angular error or flexion caused by the angle of the axle and bearing housing or axle bend. It has a high load-carrying capacity for radial load and can carry small amounts of axle load in both directions.
